The Appendix - A Mystery Organ

This small dead-end pouch attached to the large intestine is commonly known as the body part that does nothing except cause trouble!
About 1 of 10 people will suffer from appendicitis at some point, but medical experts and scientists are still not sure whether appendix normally performs any useful functions.
But recent researches have discovered some meaningful clues about it when they begun to dig up further.

William Parker, an immunologist, examined samples of normal tissue from organ donors who had healthy appendix removed during surgeries and he found out that friendly bacteria thrive in the appendix which suggests that the organ is a haven for beneficial microbes. These good bacteria help fight infection and can be considered that appendix is a part of our immune system.

With this view, appendicitis is an immune system over-reaction in much way that misdirected immune activity can bring on inflammation in people with allergies and asthma.
